Yes, that little globe valve kicked my ass. I had to swallow my pride and order a pre-made one which was done quite nicely. Learned some tricks from that one as they don't make them quite like they show in the plans, so hopefully next time I can make a good one.
Fixtures are a must for machining the pipe castings without setup nightmares. If threading, you need to decide what thread type you are going to use. I imported my taps & dies from the UK as they were a good bit cheaper than PM.
